Abstract

The invention is applicable to the technical field of transformers, and provides an oil-immersed transformer, comprising a transformer body and an insulating conduit arranged at one end in the transformer body; Insulated conduits are used to introduce endoscopic devices to detect internal faults in oil-immersed transformers. As that insulation conduit is arranged in the transformer body, the oil-immersed type transform provided by the embodiment of the invention can introduce an endoscopic device into the transformer through the insulation conduit, thereby realizing the detection of the internal fault of the oil-immersed type transformer. An oil-immersed transform according to an embodiment of that present invention, Avoid disassembling the oil drain, hanging cover and stripping bag of thetransformer, and introduce the endoscope device into the transformer by pre-implanting the insulation conduit inside the transformer, so as to determine the internal fault location and the severity of the fault, shorten the maintenance cycle of the transformer, and improve the detection efficiency of the internal fault of the oil-immersed transformer.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to an oil-immersed transformer. Background technique [0002] Transformer is one of the key equipment in the power system, and it is also the most expensive and complex equipment, which undertakes power services such as voltage conversion, power distribution and transmission. Once the power transformer fails, it may cause a sudden large-scale power outage, and even cause explosions, fires and other accidents. At present, there are more than 30,000 large power transformers of 110kV and above in operation in my country. Since the transformer is located in the center of the power grid and has a complex operating environment, it is often impacted by various adverse operating conditions and is prone to failure. The normal operation of the transformer is an important guarantee for the safe, reliable and high-quality operation of the power system. It is necessary to prevent and redu...
